the Ency. Méth. plate 325, f. 6, but the white band in the middle is narrower, and quite destitute of the circular dotted lines there expressed.

No shells require a greater accuracy of delineation than the Cones, particularly in expressing the peculiarity in the form and sculpture of their spires. I am well persuaded that a great number of the mistakes committed by authors have originated in the wretched figures contained in Favanne's work, and in the early volumes of Martini. Those of Favanne are generally so loose and inaccurate, (although remarkably well engraved,) that I do not wish, by quoting, to make them any authority; and most of the Cones figured by Martini are equally bad.

Bruguiere and Lamarck have both given the character of spirâ canaliculatâ to this species, which is altogether a mistake. The spiral whorls are all but perfectly flat, and the suture is quite closed up, although sometimes uneven; originating, as in many other shells, either from the inequalities of growth, or from an accidental sea-break, which the animal may have repaired.
